corr_coeff problem

[Joey Gao]

Hello TVB developer,

      I am trying to model brain dynamics in brain tumor patients. I found a demo named educase_TVB_braintumor but the version is too old. At the top, there's a command to import to corr_coeff, "import tvb.analyzers. correlation_coefficient as corr_coeff". But the correlation_correlation module seems have been removed. I try to use correlationcoefficients in the graph. But it seems for other aims.

       So how can I use this function in latest version of tvb? Can you give me a demo to settle thes problem to replace these code？

   # Compute the functional connectivity with the corrcoef analyzer
    corrcoeff_analyser = corr_coeff.CorrelationCoefficient(time_series=tsr)
    corrcoeff_data = corrcoeff_analyser.evaluate()
    corrcoeff_data.configure()
    FC = corrcoeff_data.array_data[..., 0, 0]

Thanks！

Hi,

Have a look at this example: https://nbviewer.thevirtualbrain.org/url/docs.thevirtualbrain.org/demos/analyze_region_corrcoef.ipynb 

Indeed, we removed (in 2019) the CorrelationCoefficient class from tvb.analyzers; it was only a wrapper over the numpy.corrcoef.

Best,

Lia.
